/* ==========================================================================
 * Side Tabs (Request Pricing / Request Quote)
 * Updated 2026-11-13.
 * - Loaded by functions.php (pw_side_tabs_enqueue) only on pages that show
 *   a tab. Markup comes from pw_side_tabs_render().
 * - Per-tab colors come from pw_side_tabs_config() through the
 *   --pw-tab-bg and --pw-tab-color custom properties.
 * - Desktop size: 50 x 180 px. Phone size: 36 x 150 px.
 * - GA4 click tracking uses the "pw-side-tab" class. Do not rename it.
